Preheat the oven to 425°F. Wash the potatoes, and peel them if desired. (I did not peel mine for this recipe.)
Cut the potatoes into evenly sized wedges, about half an inch thick. Place the wedges in a bowl and toss them with olive oil. Add the paprika, cayenne, and salt and pepper. Toss until evenly covered.
Arrange the wedges in a single layer on a greased baking sheet. Bake for 20 minutes, then flip the wedges and continue to bake for another 20-30 minutes, or until they are cooked through and golden brown.
While the fries are baking, whisk together the sour cream, lime juice, and cilantro. Chill the sauce until you're ready to serve.
Remove the fries from the oven and serve immediately with the cilantro-lime dipping sauce. If you have any leftovers, reheat the fries in the oven at 350°F for 15 minutes within one week. Enjoy!
